Video compression coding with partitioning of data into motion vector data and texture data with reversible Golomb-Rice type codes for the data. Resynchronization markers separate the data types, and the reversible coding permites decoding in both forward and backward directions to minimize data discarded due to errors.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method of encoding an image, comprising the steps of: (a) decomposing an image into texture data and other data in a data partitioned syntax for motion compensated compression; and (b) encoding said texture data with reversible Golomb-Rice type codes.
2. The method of claim 1, comprising the further steps of: (a) said other data includes motion vector data, and encoding said motion vector data with reversible Golomb-Rice type codes.
3. The method of claim 1, comprising the further steps of: (a) said other data includes header data, and encoding said header data with reversible Golomb-Rice type codes.
4. The method of claim 1, wherein: (a) said reversible Golomb-Rice type code has codewords with a symmetrical prefix portion plus a suffix portion of a first length.
5. The method of claim 1, wherein: (a) said reversible Golomb-Rice type code has codewords with a prefix portion having odd numbered bits symmetrical plus a suffix portion of a second length.
